# Diverse Violet Liquid Breathing Apparatus ## Description Welcome to your new project. Imagine what you can build here. ## Project Details - **Owner:** alexbeatsppl - **Created:** 3/17/2025 - **Last Updated:** 3/17/2025 - **Visibility:** Public - **Design Intent:** Utilize an ESP32-S3 module as the main processing unit, a USB-C connector interfaced with a CP2102 USB-to-UART converter, and an AMS1117-3.3 voltage regulator to provide a stable 3.3V supply to the ESP32. Include necessary passive components: 100nF and 10µF decoupling capacitors at the regulator output, a 100nF capacitor on the USB-C VBUS line, and a 56kΩ pull-down resistor on the USB-C CC line to ensure proper current configuration. Additional resistor networks and capacitor circuits should be implemented as needed for signal conditioning between the USB-C and USB-to-UART converter, and between the regulator and the ESP32. ## Key Components ### D1 — [LESD5D5.0CT1G](https://www.flux.ai/vasy_skral/lesd5d50ct1g.md) - Part Type: Diode - Manufacturer Part Number: LESD5D5.0CT1G - Manufacturer Name: LRC - Datasheet URL: https://datasheet.lcsc.com/lcsc/1912111437_LRC-LESD5D5-0CT1G_C383211.pdf **Pins:** - A1 [pin 1] - A2 [pin 2] ### D2 — [LESD5D5.0CT1G](https://www.flux.ai/vasy_skral/lesd5d50ct1g.md) - Datasheet URL: https://datasheet.lcsc.com/lcsc/1912111437_LRC-LESD5D5-0CT1G_C383211.pdf - Manufacturer Name: LRC - Manufacturer Part Number: LESD5D5.0CT1G - Part Type: Diode **Pins:** - A1 [pin 1] - A2 [pin 2] ### D3 — [LESD5D5.0CT1G](https://www.flux.ai/vasy_skral/lesd5d50ct1g.md) - Manufacturer Part Number: LESD5D5.0CT1G - Part Type: Diode - Datasheet URL: https://datasheet.lcsc.com/lcsc/1912111437_LRC-LESD5D5-0CT1G_C383211.pdf - Manufacturer Name: LRC **Pins:** - A1 [pin 1] - A2 [pin 2] ### J1 — [USB-C 2.0 Receptacle](https://www.flux.ai/corynrobinson/usb-c-20-receptacle.md) - Datasheet URL: https://gct.co/files/drawings/usb4105.pdf - Purchase Url: https://www.digikey.com/en/products/detail/gct/USB4105-GF-A/11198441 - Part Type: USB C - Manufacturer Name: GTC - Manufacturer Part Number: USB4105-GF-A **Pins:** - CC1 [pin 6] - CC2 [pin 12] - D- [pin 7] - D- [pin 9] - D+ [pin 8] - D+ [pin 10] - GND [pin 1] - GND [pin 2] - GND [pin 15] - GND [pin 16] - SBU1 [pin 11] - SBU2 [pin 5] - VBUS [pin 13] - VBUS [pin 4] - VBUS [pin 14] - VBUS [pin 3] ### U1 — [ESP32-S3-WROOM-1-N8R8](https://www.flux.ai/adrian95/esp32-s3-wroom-1-n8r8.md) - Part Type: Module - Manufacturer Part Number: ESP32-S3-WROOM-1-N8R8 - Manufacturer Name: Espressif Systems - Datasheet URL: https://www.espressif.com/sites/default/files/documentation/esp32-s3-wroom-1_wroom-1u_datasheet_en.pdf - License: https://creativecommons.org/licenses/by/4.0/ **Pins:** - 3V3 [pin 2] - EN [pin 3] - GND [pin 41_6] - GND [pin 41_8] - GND [pin 41_7] - GND [pin 41_3] - GND [pin 41_4] - GND [pin 40] - GND [pin 41_2] - GND [pin 41_5] - GND [pin 41_1] - GND [pin 1] - GND [pin 41_9] - IO0 [pin 27] - IO1 [pin 39] - IO10 [pin 18] - IO11 [pin 19] - IO12 [pin 20] - IO13 [pin 21] - IO14 [pin 22] - IO15 [pin 8] - IO16 [pin 9] - IO17 [pin 10] - IO18 [pin 11] - IO19 [pin 13] - IO2 [pin 38] - IO20 [pin 14] - IO21 [pin 23] - IO3 [pin 15] - IO35 [pin 28] - IO36 [pin 29] - IO37 [pin 30] - IO38 [pin 31] - IO39 [pin 32] - IO4 [pin 4] - IO40 [pin 33] - IO41 [pin 34] - IO42 [pin 35] - IO45 [pin 26] - IO46 [pin 16] - IO47 [pin 24] - IO48 [pin 25] - IO5 [pin 5] - IO6 [pin 6] - IO7 [pin 7] - IO8 [pin 12] - IO9 [pin 17] - RXD0 [pin 36] - TXD0 [pin 37] ### U2 — [AMS1117-3.3](https://www.flux.ai/jharwinbarrozo/ams1117-33.md) - Datasheet URL: https://www.lcsc.com/datasheet/lcsc_datasheet_2410122028_KEXIN-AMS1117-3-3_C369933.pdf - Part Type: Integrated Circuit - Manufacturer Name: Kexin - Manufacturer Part Number: AMS1117-3.3 **Pins:** - GND [pin 1] - TAB [pin 4] - VI [pin 3] - VO [pin 2] *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/alexbeatsppl/diverse-violet-liquid-breathing-apparatus](https://www.flux.ai/alexbeatsppl/diverse-violet-liquid-breathing-apparatus).* --- *Generated from [https://www.flux.ai/alexbeatsppl/diverse-violet-liquid-breathing-apparatus](https://www.flux.ai/alexbeatsppl/diverse-violet-liquid-breathing-apparatus)*
